At length, when the emir was sore beset by the army of the giant Agrapart, she deemed it a favourable time to betray to her father that Huon was still alive in his prison, and was ready to do battle with the giant if, as was usual in that country, the princess’s hand should be given to the victor. Both the emir and the giant agreed that their quarrel should stand or fall by single combat, and so the fight began.
Huon felt in his heart that there was more at stake than even the hand of the princess. He stood forth as the champion of Christendom amidst a host of pagans, and it behoved him to strike with all his strength. In the end the victory was his, and the giant Agrapart was overcome, but his life was spared on condition that he would serve the emir faithfully all his days, which solemn oath he took gladly. After that, Huon drew out the cup the fairy king had given him, and, having made the sign of the cross over it, it was filled with wine, and he drank of it. For he had long since repented of the lie he had told, and was clean again. Then the emir tried to drink also, but no wine would come.
‘You must forsake your false gods, and be a Christian such as I am,’ said Huon, ‘and if you like not fair words you shall see how an armed host pleases you;’ but, as was natural, the ruler of Babylon was not the man to be moved by such persuasions. He angrily bade Huon cease, and to speak to him no more on the matter or all the hosts of Charlemagne himself should not avail to save his head.
‘You will repent you too late,’ said Huon, and blew his horn.
At first the emir and his courtiers began to dance and sing wildly, they knew not wherefore, while in the wood far away Oberon heard the sound. ‘Huon, my friend, has great need of me,’ he thought to himself, ‘and his ill-doings have been punished enough, so I will pardon him, for there is not in all the world so noble a man. Therefore I wish myself at his side, with a thousand men behind me.’ And in another moment, no man could tell how, Oberon and his men were within the walls of Babylon. The guards of the palace fell before them on every hand, till at last they reached the emir himself.
‘He is yours to spare or to slay,’ said Oberon, and once more the knight gave the Paynim his choice.
‘Be a Christian or you die,’ said Huon, and the emir made answer:
‘I will never forsake my own.’ They were the last words he spoke, for his head rolled upon the floor. After that Huon cut off the emir’s beard and pulled out four of his teeth, and hid them in the beard of his old friend Gerames, who had lately returned to Babylon.
